# C Program to Find and Print Sum of all Digit of any Number

Here we will learn about how to create a program in C that will ask from the user to enter any number (at run-time) as input, and then calculate and print the sum of all the digit present in that given number. Here is the program:

#include<stdio.h> #include<conio.h> int main() { int num, sum=0, rem; printf("Enter any number: "); scanf("%d", &num); while(num>0) { rem = num%10; sum = sum + rem; num = num/10; } printf("\nSum of Digit = %d", sum); getch(); return 0; }

As the program was written under **Code::Blocks** IDE, therefore after successful build and run, here is the output:

Supply any number say 2358 and press ENTER key to see the sum of all the digit as output or result. Here is the second snapshot of the sample run:

Here are the list of some main steps used in above program:

- Receive any number from user at run-time as input
- Create a
**while**loop that runs until the number is greater than 0 - Inside the
**while**loop, find the digit of the number by applying remainder or modulous (%) operator, that is use**num%10**which gives the last digit of the number and will be initialized to the variable**rem**. Initialize**sum+rem**to**sum**variable. Never forgot to initialize 0 to**sum**at start of the program. And then divide the number with 10 and continue to check and do the same operation - Let's suppose that the user has supplied 247 as input
- The variable
**num**holds the value 247 which is greater than 0, then program flow goes inside the**while**loop, and**num%10**or**247%10**or**7**will be initialized to**rem**. And**sum+rem**or**0+7**or**7**will be initialized to the variable**sum**. And finally**num/10**or**247/10**or**24**will be initialized to**num** - At second run of the
**while**loop, num holds 24 which is again greater than 0, then the program flow again goes inside the**while**loop and do the same task in same way as done at first run of the**while**loop - At last that is after coming out from the
**while**loop, the variable**sum**holds the value that is equal to the sum of all the digit of that given number by user at start of the program
